说明

一般說明

一个适用于通过 LC-MS/MS 对甲氨蝶呤患者血清样品进行治疗性药物监测分析的内标。甲氨蝶呤用于治疗癌症和自身免疫性疾病，是一种抗代谢物和抗叶酸药物，由临床实验室进行监控，以确保患者服用量维持在该药物的治疗范围内。Snap-N-Spike^® 解决方案格式可让实验室不需要对氨甲蝶呤等有害物质进行称重操作，显着降低处理剧毒粉末相关的职业暴露危害，并提供在使用前立即掺入所选基质的功能。

應用

• Application in leukemia research: Methotrexate-D₃ is utilized as an internal standard in LC-MS/MS analysis to monitor the bioavailability and metabolic pathways of thioguanosine and methylthioinosine in children with acute lymphoblastic leukemia, supporting its use in pediatric oncology and pharmacokinetics studies (Han et al., 2022).


• Enhancement of drug monitoring techniques: Employed in high-throughput MALDI-isotope dilution mass spectrometry, Methotrexate-D₃ allows for the ultrafast and selective quantification of methotrexate in human plasma, proving essential for optimizing therapeutic regimens in cancer treatment (Meesters et al., 2011).
